Children's mental health emergencies--part 2: emergency department evaluation and treatment of children with mental health disorders

Pediatric Agitation in the Emergency Department: A Survey of Pediatric Emergency Care Coordinators

OBJECTIVE

Acute agitation episodes in the emergency department (ED) can be distressing for patients, families, and staff and may lead to injuries. We aim to understand availability of ED resources to care for children with acute agitation, perceived staff confidence with agitation management, barriers to use of de-escalation techniques, and desired resources to enhance care.

METHODS

We conducted a survey of pediatric emergency care coordinators (PECCs) in EDs in Massachusetts, Rhode Island, and Los Angeles County, California.

RESULTS

PECCs from 63 of 102 (61.8%) EDs responded. PECCs reported that ED staff feel least confident managing agitation due to developmental delay (DD) or autism spectrum disorder (ASD) (52.4%). Few EDs had a separate space to care for children with mental health conditions (22.5%), a standardized agitation scale (9.6%), an agitation management guideline (12.9%), or agitation management training (24.2%). Modification of the environment was not perceived possible for 42% of EDs. Participants reported that a barrier to the use of the de-escalation techniques distraction and verbal de-escalation was perceived lack of effectiveness (22.6% and 22.6%, respectively). Desired resources to manage agitation included guidelines for medications (82.5%) and sample care pathways (57.1%).

CONCLUSIONS

ED PECCs report low confidence in managing agitation due to DD or ASD and limited pediatric resources to address acute agitation. Additional pediatric-specific resources and training, especially for children with DD or ASD, are needed to increase clinician confidence in agitation management and to promote high-quality, patient-centered care. Training programs can focus on the early identification of agitation and the effective use of non-invasive de-escalation strategies.

Disparities in Pharmacologic Restraint Use in Pediatric Emergency Departments

OBJECTIVES

Emergency department (ED) utilization by children with mental and behavioral health (MBH) conditions is increasing. During these visits, pharmacologic restraint may be used to manage acute agitation. Factors associated with pharmacologic restraint use are not well described.

METHODS

This was a retrospective cohort study of ED visits from the Pediatric Health Information System database, 2010-2020. We included visits by children 3-21 years with a primary MBH diagnosis and identified visits with pharmacologic restraint. Regression models were used to analyze the association between patient- and hospital-level factors and restraint.

RESULTS

Of 545 800 ED MBH visits over the study period, 22 194 visits (4.1%) involved pharmacologic restraint use. In multivariable analysis, restraint was associated with ages 18-21 years (odds ratio [OR], 1.88; 95% confidence interval [CI], 1.59-2.22), male sex (OR, 1.25; 95% CI, 1.16-1.34), Black race (OR, 1.22; 95% CI, 1.09-1.35), visits starting overnight (OR, 1.68; 95% CI, 1.45-1.96), or the weekend (OR, 1.26; 95% CI, 1.22-1.30), and repeat ED visits (OR, 1.31; 95% CI, 1.17-1.47). Every 100-visit increase in average annual MBH volume was associated with a 0.09% decrease in restraint (95% CI, -0.15 to -0.04) with no significant association between average annual ED volume and restraint (95% CI, -0.25 to 0.25).

CONCLUSIONS

For children in the ED with MBH conditions, ages 18-21 years, male sex, Black race, visits starting overnight or the weekend, and repeat ED visits were associated with pharmacologic restraint. These results can inform strategies to reduce restraint use and ensure safe and equitable ED care.

Do All Adult Psychiatric Patients Need Routine Laboratory Evaluation and an Electrocardiogram?

BACKGROUND

Acute psychiatric presentations account for a significant number of emergency department (ED) visits. These patients require assessment by the emergency physician and often need further evaluation by a psychiatrist, who may request routine laboratory evaluation and an electrocardiogram (ECG).

CLINICAL QUESTION

Do all adult psychiatric patients need routine laboratory evaluation and an ECG?

EVIDENCE REVIEW

Studies retrieved included 2 prospective, observational studies and 7 retrospective studies. These studies evaluate the utility of laboratory analysis in all patients presenting a psychiatric complaint and its impact on patient management and disposition.

CONCLUSION

Based upon the available literature, routine laboratory analysis and ECG for all patients presenting with a psychiatric complaint are not recommended. Clinicians should consider the individual patient, clinical situation, and comorbidities when deciding to obtain further studies such as laboratory analysis. © 2022 Elsevier Inc.

Pharmacologic Restraint Use During Mental Health Visits in Pediatric Emergency Departments

OBJECTIVES

To evaluate the trends and hospital variation in the use of pharmacologic restraint among pediatric mental health visits in the emergency department (ED).

STUDY DESIGN

We examined ED visits with a mental health diagnosis in patients aged 3-21 years at children's hospital EDs from 2009 to 2019. We calculated the frequency of pharmacologic restraint use and determined visit characteristics associated with restraint use. We calculated cumulative percent change for visits with restraints and for all mental health visits. We used logistic regression to test trends over time and evaluate hospital variation in the frequency of restraint use.

RESULTS

We identified 389 885 mental health ED visits (54.9% female, median age 14.3 years) and 13 643 (3.5%) visits with pharmacologic restraint use. Characteristics associated with pharmacologic restraint use were late adolescent age (18-21 years), male sex, Black race, non-Latino ethnicity, public insurance, and admission to the hospital (P < .001). During the study period, both mental health ED visits increased by 268% and mental health ED visits with pharmacologic restraint use increased by 370%. The rate of pharmacologic restraint in this patient population remained constant. Hospital use of pharmacologic restraint for mental health visits varied significantly across hospitals (1.6%-11.8%, P < .001).

CONCLUSIONS

Pediatric mental health ED visits with and without pharmacologic restraint are increasing over time. In addition, the overall number of pharmacologic restraint use has increased threefold. Significant hospital variation in pharmacologic restraint use signifies an opportunity for standardization of care and restraint reduction.

Reducing length of stay and return visits for emergency department pediatric mental health presentations

BACKGROUND

Variability in expertise and risk tolerance among emergency departments (ED) clinicians, when assessing and managing pediatric mental health presentations, leads to increased resource utilization. HEARTSMAP is a validated electronic tool that supports ED clinicians in psychosocial assessments and disposition decision making.

METHODS

We used interrupted time series analysis (September 2016-December 2019) and multivariable regressions to measure the impact of integrating HEARTSMAP into ED practice on pediatric mental health presentations length of stay and return visits, at two pediatric EDs. The intervention site used HEARTSMAP trained ED clinicians to assess and manage mental health presentations, and reported bi-weekly ED median length of stay and 30 days-return visits for 15 months and a year, during passive and active implementation of HEARTSMAP, respectively. The control site used psychiatric nurses to assess and manage patients and was only exposed to passive implementation.

RESULTS

HEARTSMAP average uptake was on average 47.4% (range 23.8-74.6%) during active implementation at the intervention site, while the control site showed no uptake throughout the study period. Incremental HEARSTMAP (each percent increase) use was associated with a reduction of 1.8 min (95% CI 0.8-2.9 in ED length of stay and 0.3% (95% CI 0.2-0.5 in 30-day return visit rate. This translates to an adjusted average reduction of 85.3 min in ED length of stay and 15.2% in 30-day return visits for youth with mental health presentations.

CONCLUSION

Use of HEARTSMAP in the ED can decrease length of stay and return visits for emergency pediatric mental health visits, in a fixed-resource setting.

Focused Medical Assessment of Pediatric Behavioral Emergencies

There is no uniformly accepted standard of care for medical clearance of pediatric patients with psychiatric complaints. Emerging data argue for a thorough history and physical examination and against routine laboratory testing. The differential diagnosis of patients presenting with psychiatric health complaints is extensive and includes both medical and psychiatric disorders. Providers should remain mindful of anchoring or diagnosis momentum bias when caring for these patients, especially patients with a psychiatric history.

Identifying Undiagnosed Pediatric Mental Illness in the Emergency Department

BACKGROUND

It is well known that pediatric psychiatric patients frequent emergency department (ED), but the number of patients with undiagnosed psychiatric illness presenting to an ED is not well known. Identification and referral of these patients may provide an opportunity for improved patient care. The primary study objective was to identify a tool that can screen for unsuspected psychiatric illness in pediatric patients who present to the ED with non-psychiatric-related complaints.

METHODS

The MINI International Neuropsychiatric Interview for Children and Adolescents screening tool was administered to 200 pediatric consenting patients and guardians. The inclusion criteria were English-speaking patients who presented in the ED with a nonpsychiatric complaint who were stable and able to communicate. The study was conducted in a level 1 trauma center ED of an inner-city hospital that serves a predominantly African American and Hispanic population. This study was institutional review board approved.

RESULTS

The study populations consisted of 53% African American (107), 45% Hispanic (90), 1% white (2), and 0.5% Asian (1). Their age range was divided, with 49% between 12 and 14 years (98) and 51% between 15 and 17 years (102). The sex was evenly split, with 50% male (100) and 50% female (100). The 41% who did screen positive for an undiagnosed mental illness had a range of diagnoses. The top modules with positive results were oppositional defiant (13.5%, 27), attention-deficit/hyperactivity disorder (13%, 25), depression (10%, 11), conduct disorder (9%, 19), and anxiety (5%, 11).

CONCLUSIONS

The pediatric Mini International Neuropsychiatric Interview was effective in screening for undiagnosed mental illness in pediatric patients who presented to the ED with no psychiatric-related illness. The screening tool indicated that 41% of pediatric patients screened positive for an undiagnosed mental illness, with attention deficit-related disorders being the most widely seen. Further study should be conducted to test the tools used in a range of ED settings.

Emergency Department Medical Clearance of Patients with Psychiatric or Behavioral Emergencies, Part 1

Patients presenting to the emergency department with mental illness or behavioral complaints merit workup for underlying physical conditions that can trigger, mimic, or worsen psychiatric symptoms. However, interdisciplinary consensus on medical clearance is lacking, leading to wide variations in quality of care and, quite often, poor medical care. Psychiatry and emergency medicine specialty guidelines support a tailored, customized approach. This article summarizes best-practice approaches to the medical clearance of patients with psychiatric illness, tips on history taking, system reviews, clinical or physical examination, and common pitfalls in the medical clearance process.

Emergency Department Medical Clearance of Patients with Psychiatric or Behavioral Emergencies, Part 2: Special Psychiatric Populations and Considerations

Patients who present to the emergency department (ED) with mental illness or behavioral complaints merit workup for underlying physical conditions that can trigger, mimic, or worsen psychiatric symptoms. However, there are wide variations in quality of care for these individuals. Psychiatry and emergency medicine specialty guidelines support a tailored, customized approach to patients. Our group has long advocated a dynamic comanagement approach for medical clearance in the ED, and this article summarizes best-practice approaches to the medical clearance of patients with psychiatric illness, tips on history taking, system reviews, clinical/physical examination, and common pitfalls in the medical clearance process.

A Systematic Review of Instruments to Identify Mental Health and Substance Use Problems Among Children in the Emergency Department

OBJECTIVE

Specialized instruments to screen and diagnose mental health problems in children and adolescents are not yet standard components of clinical assessments in emergency departments (EDs). We conducted a systematic review to investigate the psychometric properties, accuracy, and performance metrics of instruments used in the ED to identify pediatric mental health and substance use problems.

METHODS

We searched seven electronic databases and the gray literature for psychometric validation studies, diagnostic studies, and cohort studies that assessed any instrument to screen for or diagnose mental illness, emotional or behavioral problems, or substance use disorders. Studies had to include children and adolescents with mental health presentations or positive screens for substance use. Two reviewers independently screened studies for relevance and quality. Diagnostic study quality was assessed with the four QUADAS-2 domains. Psychometric study quality was assessed with published criteria for instrument reliability, validity, and usability. We present a descriptive analysis of the reported psychometric properties and diagnostic performance of instruments for each study.

RESULTS

Of the 4,832 references screened, 14 met inclusion criteria. Included studies evaluate 18 instruments for identifying suicide risk (six studies), alcohol use disorders (six studies), mood disorders (one study), and ED decision making (need for assessment, admission; one study). Nine studies include a psychometric focus but quality varies, with no studies fully meeting criteria for reliability, validity, and usability. Seven studies examine diagnostic performance of an instrument, but no study has a low risk of bias for all QUADAS-2 domains. The HEADS-ED instrument has good inter-rater reliability (r = 0.785) for identifying general mental health problems and modest evidence for ruling in patients requiring hospital admission (positive likelihood ratio [LR+] = 6.30). Internal consistency (reliability) varies for instruments to screen for suicide risk (α = 0.46-0.97), and no instruments have both high sensitivity and high specificity. The Ask Suicide-Screening Questions (ASQ) is highly sensitive (98%) and has strong evidence for ruling out risk (negative likelihood ratio [LR-] = 0.04). Among screening instruments for alcohol use disorders, internal consistency is high for the consumption subscale of the Alcohol Use Disorders Identification Test (α = 0.83-0.88) and the Adolescent Drinking Index (α = 0.92). Both instruments also had sound internal validity. Diagnostically, a two-item instrument based on DSM-IV criteria is the most accurate in identifying patients with a disorder (area under the curve = 0.89) and has modest evidence for ruling in and out risk (LR+ = 8.80, LR- = 0.13).

CONCLUSIONS

From available evidence, we recommend that ED clinicians use 1) the HEADS-ED to rule in ED admission among pediatric patients with visits for mental health care, 2) the ASQ to rule out suicide risk among pediatric patients with any visit type, and 3) the DSM-IV two-item instrument to rule in/rule out alcohol use disorders among pediatric patients currently using alcohol. These instruments require minimal to no training or time commitment. We also recommend that clinicians become familiar with each instrument's psychometric properties to understand the quality of the evidence base. In this review, however, we identify methodologic limitations in the evidence base. To develop a robust evidence base, additional research is necessary.

Pediatric Use of Emergency Medical Services: The Role of Chronic Illnesses and Behavioral Health Problems

OBJECTIVE

The increasing use of prehospital emergency medical services (EMS) and its contribution to rising emergency department use and healthcare costs point to the need for better understanding factors associated with EMS use to inform preventive interventions. Understanding patient factors associated with pediatric use of EMS will inform pediatric-specific intervention. We examined pediatric patient demographic and health factors associated with one-time and repeat use of EMS.

METHODS

We reviewed data from Baltimore City Fire Department EMS patient records over a 23-month period (2008-10) for patients under 21 years of age (n = 24,760). Repeat use was defined as involvement in more than one EMS incident during the observation period. Analyses compared demographics of EMS users to the city population and demographics and health problems of repeat and one-time EMS users. Health comparisons were conducted at the patient and incident levels of analysis.

RESULTS

Repeat users (n = 1,931) accounted for 9.0% of pediatric users and 20.8% of pediatric incidents, and were over-represented among the 18-20 year age group and among females. While trauma accounted for approximately one-quarter of incidents, repeat versus one-time users had a lower proportion of trauma-related incidents (7.2% vs. 26.7%) and higher proportion of medical-related incidents (92.6% vs. 71.4%), including higher proportions of incidents related to asthma, seizures, and obstetric/gynecologic issues. In patient-level analysis, based on provider or patient reports, greater proportions of repeat compared to one-time users had asthma, behavioral health problems (mental, conduct and substance use problems), seizures, and diabetes.

CONCLUSIONS

Chronic somatic conditions and behavioral health problems appear to contribute to a large proportion of the repeat pediatric use of this EMS system. Interventions may be needed to engage repeat users in primary care and behavioral health services, to train EMS providers on the recognition and management of behavioral health emergencies, and to improve family care and self-management of pediatric asthma and other chronic conditions.

Down the Rabbit Hole: Emergency Department Medical Clearance of Patients with Psychiatric or Behavioral Emergencies

Patients presenting with behavior or psychiatric complaints may have an underlying medical disorder causing or worsening their symptoms. Misdiagnosing a medical illness as psychiatric can lead to increased morbidity and mortality. A thorough history and physical examination, including mental status, are important to identify these causes and guide further testing. Laboratory and ancillary testing should be guided by what is indicated based on clinical assessment. Certain patient populations and signs and symptoms have a higher association with organic causes of behavioral complaints. Many medical problems can present with or exacerbate psychiatric symptoms, and a thorough medical assessment is imperative.

Trends in Pediatric Emergency Department Utilization for Mental Health-Related Visits

OBJECTIVE

To describe trends in utilization of pediatric emergency department (PED) resources by patients with mental health concerns over the past 11 [corrected] years at a tertiary care hospital.

STUDY DESIGN

We conducted a retrospective cohort study of tertiary PED visits from 2002 [corrected] to 2012. All visits with chief complaint or discharge diagnosis related to mental health were included. Variables analyzed included number and acuity of mental health-related visits, length of stay, waiting time, admission rate, and return visits, relative to non-mental health [corrected] PED visits. Descriptive statistics were used to summarize the results.

RESULTS

We observed a 47% increase in the number of mental health presentations compared with a 27.5% [corrected] increase in the number of total visits to the PED over the study period. Return visits represented a significant proportion of all mental health-related visits (32.2% [corrected] yearly). The proportion of mental health visits triaged to a high acuity level has decreased whereas the proportion of visits triaged to the mid-acuity level has increased. Length of stay for psychiatric patients was significantly longer than for visits to the PED in general. We also observed a 53.7% [corrected] increase in the number of mental health-related visits resulting in admission.

CONCLUSION

Mental health-related visits represent a significant and growing burden for the emergency department at a tertiary care PED. These results highlight the need to reassess the allocation of health resources to optimize acute management, risk assessment, and linkage to mental health services upon disposition from the PED.

Characteristics and disposition of youth referred from schools for emergency psychiatric evaluation

We aimed to describe the characteristics and disposition of youth referred from schools to the emergency department (ED) for psychiatric evaluations. Consecutive 12-month records of ED psychiatric consultations at a large urban hospital from 07.01.2009 to 06.30.2010 were retrospectively analyzed. School-initiated referrals were deemed inappropriate if youth were discharged from the ED without any recommended mental health follow-up. Of the 551 psychiatric ED evaluations, 243 (44.1%) were initiated by schools. Of all school referrals, only 19 (7.8%) children were psychiatrically hospitalized, 108 (44.4%) were discharged from the ED with a follow-up appointment; and 116 (47.7%) were discharged without arranged follow-up. Those with a chief complaint of "suicidality" (n = 109, 44.9%) were more likely to be discharged without arranged follow-up than youth with other presenting complaints (56.0 vs. 41.0%, p = 0.021). Altogether, only 37 (18.5%) of 200 school-referred youth with information were evaluated by a school nurse, social worker, or other professional before being sent to the ED. Students without in-school screening were significantly more frequently discharged without follow-up than students with in-school evaluations prior to the ED referral (51.5 vs. 27.0%, p = 0.0070; odds ratio = 2.87 (95% CI 1.30-6.31). Multivariate predictors of inappropriate school referrals of youth discharged without any outpatient follow-up were higher Children's Global Assessment Scale score (p < 0.0001), absent in-school evaluation (p = 0.0069), absent prior psychiatric history (p = 0.011) and absent current psychotropic medication treatment (p = 0.012) (r(2) = 0.264%, p < 0.0001). Altogether 44.1% of ED consultations were school referred, of which 47.7% were potentially inappropriate for the emergency setting. In-school screening, which occurred infrequently, reduced unnecessary evaluations by 52%.

Emergency department visits in the United States for pediatric depression: estimates of charges and hospitalization

OBJECTIVES

The objective of this study was to calculate national estimates of depression-related emergency department (ED) visits and associated health care resource use among children and adolescents 17 years or younger. Another goal was to explore the effects of certain sociodemographic and health care system factors and comorbidities on ED charges and subsequent hospitalization in the United States.

METHODS

The authors analyzed data from the 2006 and 2009 National Emergency Department Sample (NEDS), the largest source of U.S. ED data. ED visits with all listed diagnoses (i.e., principal diagnosis plus secondary conditions) of depression were identified using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes 293.83, 296.2X, 296.3X, 300.4, and 311. Population-based estimates of ED visits, hospitalization, resource use, comorbidities, and demographics associated with pediatric depression were calculated. Potentially significant covariate associations were also explored using ED charges and hospital admission from the ED.

RESULTS

The 2006 and 2009 NEDS sample contained 365,713 ED visits for pediatric depression; the majority were made by adolescents (87.9%). Of these, 27.2% were admitted to the hospital, 69.5% were treated and released, and <0.1% died in ED. The ED charges in 2012 U.S. dollars summed to a hospital bill of $443.8 million, with the ED plus inpatient charges ($1.2 billion) being more than double that amount. The median inpatient length of stay (LOS) was 4.0 days. Suicide and intentional self-inflicted injury were attempted by 31.4% of the patients. Attention-deficit, conduct, and disruptive disorders; anxiety disorders; substance use disorders; asthma; and infections were the most common comorbidities. In year 2009, a higher number of diagnoses, older age, being female, key comorbidities, and suicide and intentional self-inflicted injury were significantly associated with higher ED charges (all p < 0.05). Increased odds of hospital admission from the ED were significantly associated with a higher number of diagnoses, key comorbidities, and suicide and intentional self-inflicted injury (all p < 0.05).

CONCLUSIONS

Pediatric depression is common in the ED and is associated with significant burden to the health care system. Certain factors such as a higher number of diagnoses, key comorbidities, and suicide and intentional self-inflicted injury are associated with increased health care costs and resource use. Special attention should be given to these factors, when present.

Emergency psychiatric care for children and adolescents: a literature review

OBJECTIVES

Over the years, increasing numbers of children and adolescents have sought help for acute psychiatric problems. The responses to this treatment-seeking behavior are heterogeneous in different settings and nations. This review aimed to provide an answer to the questions "which care should be offered to children and adolescents presenting with a psychiatric emergency or crisis and how should it be organized."

METHODS

We committed a literature review to find out if any recommendations can be made regarding the organization of emergency care for children and adolescents with acute mental health problems.

RESULTS

The lack of a clear definition of emergencies or urgencies hampered this review; we note the differences between adult and child or adolescent psychiatry. The theoretical models of care found in the literature are built up from several process and structural components, which we describe in greater detail. Furthermore, we review the main service delivery models that exist for children and adolescents.

CONCLUSIONS

Currently, emergency psychiatric care for children and adolescents is practiced within a wide range of care models. There is no consensus on recommended care or recommended setting for this population. More research is needed to make exact recommendations on the standardization of psychiatric care for young people in emergency settings.

Prevalence of suicidality in asymptomatic adolescents in the paediatric emergency department and utility of a screening tool

OBJECTIVE

Many authorities recommend screening adolescents for risk of suicide. The ED is a potential setting for such screening. The aim of this study is to explore the use of the Risk of Suicide Questionnaire (RSQ) as a screening tool for suicidality in patients who come to the ED without mental health concerns and without recent mental health history. The Suicide Ideation Questionnaire (SIQ) was the comparison standard.

METHODS

A cross-sectional convenience sample of overtly psychiatrically asymptomatic adolescents presenting to a large paediatric ED underwent both the RSQ and SIQ. Adolescents with positive screens underwent formal assessment by mental health practitioners.

RESULTS

Two hundred and one patients were identified and 110 consented to participate. One hundred participants completed both questionnaires. Twenty-two per cent of participants had positive RSQ (95% CI 14-31%). No adolescent yielded a positive SIQ: prevalence of suicidality was 0.0% (95% CI 0.0-3.6%). No participant showed suicidal ideation on formal review. One question in the RSQ - 'Has something very stressful happened to you in the past few weeks?' - accounted for the majority of false positive screens.

CONCLUSION

The prevalence of suicidal ideation in asymptomatic patients presenting to this paediatric ED is very low. Using this selection method, the RSQ could not be validated, but would be unlikely to be suitable for screening this low-risk population with a high false positive rate.

A systematic review of crisis interventions used in the emergency department: recommendations for pediatric care and research

OBJECTIVE

In this systematic review, we evaluated the effectiveness of emergency department (ED)-based management interventions for mental health presentations with an aim to provide recommendations for pediatric care.

METHODS

A search of electronic databases, references, key journals, and conference proceedings was conducted, and primary authors were contacted. Experimental and observational studies that evaluated ED crisis care with pediatric and adult patients were included. Adult-based studies were evaluated for potential translation to pediatric investigation. Pharmacological-based studies were excluded. Inclusion screening, study selection, and methodological quality were assessed by 2 independent reviewers. One reviewer extracted the data, and a second checked for completeness and accuracy. Presentation of study outcomes included odds ratios (ORs) and mean differences (MDs) with 95% confidence intervals (CI). Meta-analysis was deferred due to clinical heterogeneity in intervention, patient population, and outcome.

RESULTS

Twelve observational studies were included in the review with pediatric (n = 3), and adult or unknown (n = 9) aged participants. Pediatric studies supported the use of specialized care models to reduce hospitalization (OR, 0.45; 95% CI, 0.33-0.60), return ED visits (OR, 0.60; 95% CI, 0.28-1.25), and length of ED stay (MD, -43.1 minutes; 95% CI, -63.088 to -23.11 minutes). In an adult study, reduced hospitalization was reported in a comparison of a crisis intervention team to standard care (OR, 0.59; 95% CI, 0.43-0.82). Five adult-based studies assessed triage scales; however, little overlap in the scales investigated, and the outcomes measured limited comparability and generalizability for pediatrics. In a comparison of a mental health scale to a national standard, a study demonstrated reduced ED wait (MD, -7.7 minutes; 95% CI, -12.82 to -2.58 minutes) and transit (MD, -17.5 minutes; 95% CI, -33.00 to -1.20 minutes) times. Several studies reported a shift in triage scores of psychiatric patients dependent on the scale or nurse training (psychiatric vs emergency), but linkage to system- or patient-based outcomes was not made, limiting clinical interpretation.

CONCLUSIONS

Pediatric studies have demonstrated that the use of specialized care models for mental health care can reduce hospitalization, return ED visits, and length of ED stay. Evaluation of these models using more rigorous study designs and the inclusion of patient-based outcomes will improve this evidence base. Adult-based studies provided recommendations for pediatric research including a focus on triage and restraint use.

Who comes back? Characteristics and predictors of return to emergency department services for pediatric mental health care

OBJECTIVES

The objective of this study was to investigate predictors of emergency department (ED) return visits for pediatric mental health care. The authors hypothesized that through the identification of clinical and health system variables that predict return ED visits, which children and adolescents would benefit from targeted interventions for persistent mental health needs could be determined.

METHODS

Data on 16,154 presentations by 12,589 pediatric patients (<or=17 years old) were examined from 2002 to 2006, using the Ambulatory Care Classification System (ACCS), a provincewide database for Alberta, Canada. Multivariable logistic regressions identified predictors, while survival analyses estimated time to ED return.

RESULTS

In the multivariable analysis, there were four patient factors significantly associated with ED return. Male sex (odds ratio [OR] = 0.78; 99% confidence interval [CI] = 0.69 to 0.89) was associated with a lower rate of return, as was child age. The likelihood of ED return increased with age. Children <or=5 years (OR = 0.26; 99% CI = 0.14 to 0.46) and between ages 6 and 12 (OR = 0.64; 99% CI = 0.51 to 0.79) were less likely to return, compared to 13- to 17-year-olds. Patients with families receiving full assistance for covering government health care premiums were more likely to return compared to those with no assistance (OR = 1.59; 99% CI = 1.33 to 1.91). Patients were more likely to return if their initial presentation was for a mood disorder (OR = 1.72; 99% CI = 1.46 to 2.01) or psychotic-related illness (OR = 2.53; 99% CI = 1.80 to 3.56). There were two modest health care system predictors in the model. The likelihood of return decreased for patients triaged as nonurgent (OR = 0.62; 99% CI = 0.45 to 0.87) versus those triaged as urgent (level 3 acuity) and increased for patients with visits to general (vs. pediatric) EDs (OR = 1.25; 99% CI = 1.03 to 1.52). ED region (urban vs. rural) did not predict return. Within 72 hours of discharge, 6.1 and 8.7% of patients diagnosed with a mood disorder and psychotic-related illness, respectively, returned to the ED. Throughout the study period, 28.5 and 36.6% of these diagnostic populations, respectively, returned to the ED.

CONCLUSIONS

Among children and adolescents who accessed the ED for mental health concerns, being female, older in age, in receipt of social assistance, and having an initial visit for a mood disorder or psychotic-related illness were associated with return for further care. How patient presentations were triaged and whether visits were made to a pediatric or general ED also affected the likelihood of return.
